MASTERVOLT CombiMaster 12/3500-200 120V: The Ultimate Inverter/Charger for Uninterrupted Power

Experience unparalleled power reliability and efficiency with the MASTERVOLT CombiMaster 12/3500-200 (120V), the definitive all-in-one solution for your mobile and off-grid power needs. Engineered for the most demanding marine and vehicle applications, this compact powerhouse seamlessly combines a powerful pure sine wave inverter, an advanced battery charger, and an automatic transfer system into a single, robust unit. Say goodbye to complex power systems and hello to effortless, dependable energy wherever your journey takes you.

The CombiMaster is designed to be the heart of your electrical system, providing a stable 120V AC output from your 12V battery bank. With a continuous power rating of 3500W, it can effortlessly run demanding appliances like air conditioners, microwaves, and power tools, while its pure sine wave output ensures the safe and optimal performance of sensitive electronics such as laptops, entertainment systems, and modern galley equipment.

What truly sets the CombiMaster apart is its intelligent and robust design. The integrated 200A battery charger is a powerhouse in its own right, utilizing Mastervolt’s acclaimed 3-step+ charging algorithm to rapidly and safely replenish your batteries. This advanced charging profile is suitable for all battery chemistries, including traditional Flooded, Gel, AGM, and modern Lithium-Ion, ensuring maximum performance and extending the lifespan of your valuable battery bank.

One of the most innovative features is the Power Assist function. When connected to a limited shore power or generator supply, the CombiMaster intelligently supplements the incoming AC power with energy from your batteries, preventing overloaded breakers and ensuring you can run heavy loads without interruption. The ultra-fast automatic transfer switch (under 20 milliseconds) guarantees a seamless transition between AC sources and the inverter, so your computers and other sensitive equipment won´t even notice the switch. This provides a truly uninterruptible power supply (UPS) functionality.

Built for the modern era of smart integration, the CombiMaster is compatible with MasterBus, CZone, and NMEA 2000 communication protocols, allowing for seamless integration into a complete digital switching and monitoring system. This enables you to control and monitor your entire power system from a single display, providing ultimate control and peace of mind. Despite its immense power, the CombiMaster is surprisingly compact and lightweight, making installation straightforward even in tight spaces.
